If you have a question about getting into a waitlisted class

<p>I am #5 on the waitlist for a Chem 140A discussion AND there are 5 or 6 openings. How can that be? Are these spots reserved? Will they add me later? The whole thing is just very odd; for the lecture there are now openings in all discussions except one which has maintained its waitlist of 18.
Thanks, I did not want to start another waitlist thread!</p>
